MORE-DOC

Often it is assumed in the text provided by :more-doc name that
you have read the text provided by :doc name.

:More-doc just continues spewing out at you the documentation string
provided with a definition. If the user has done his job, :doc will
probably remind you of the basics and :more-doc, if read after :doc,
will address obscure details that are nevertheless worth noting.

When :more-doc types ``(type :more for more, :more! for the rest)''
you can get the next block of the continuation by typing :more or
all of the remaining blocks by typing :more!. See more.
